ABSTRACT:
The invention relates flash memory programming techniques. An object of the invention is to provide a flash memory programming technique avoiding problems of the known state of the art and in particular, saving a significant amount of time during the development and/or production phases of any equipment containing flash memory devices and also saving time during an updating or upgrading procedure of such an equipment already being in use. Accordingly, the invention proposes for programming a flash memory device to program only differences in information between data already stored in the flash memory device and new data to be stored.
